BRAKE MECHANISM FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters ZPatent No. 700,818, dated. May27, 1902.

Original application filed February 9, 1901, Serial No. 46,654- Dividedand this application filed October 3, 1901. Serial No. 77,398. (Nomodel.)

To all whom, it may concern:

Be it known that 1, CHARLES W. POWELL,

a citizen of the United States, residing at Green Island, county ofAlbany, and State of New York, have invented certain new and usefulImprovements in Brake Mechanism for Railway-Oars, of which the followingis a specification.

The invention relates to such improvements; and it consists of the novelconstruction and combination of parts hereinafter de scribed andsubsequently claimed.

Reference may be had to the accompanying drawings, and the referencecharacters marked thereon, which form a part of this specification.

Similar characters refer to similar parts in both figures.

Figure 1 of the drawingsis a view in side elevation of a truck-frameprovided with my improved brake mechanism. Fig. 2 is a top plan viewillustrating the arrangement of the brakes and brake-operating leversand connections, the truck-frame being omitted.

This application is adivision of an application filed heretofore by meFebruary 9, 1901, No. 46,654, for improvements in car-trucks.

The present invention relates more particularly to brake mechanismadapted for use upon electric-car trucks.

1 represents the truck-frame, which may be of any known form, no claimbeing made herein to the particular forni of frame herein sh0wn,whichisparticularly shown,described, and claimed in the said priorapplication, of which this is a division. The truck-frame is mountedupon and supported by the axles 2,

upon which are fixed the wheels 3 in the usual manner. upon thebrake-beams 31, one at each end of the truck outside the wheels. Thebrakebeams are suspended by links 32 from the wheel-supported frame ofthe truck in the usual manner. Each brake-beam carries a The brake-shoes30 are mounted.

brake-beam at 37 and provided at its other end with means for connectingthe same with the brake -operating shaft, as the link 38, which mayconnect with a chain leading to said shaft, said chain and shaft beingomitted from the drawings. An intermediate portion of the lever 36 isconnected by link 39 with an extension 10 of one of the levers 33.

From an inspection of Fig. 2 it will be seen that a pulling forceexerted upon the link 38 at either end of the car will operate toproduce a pull in the same direction upon the rods 35, which rods actingas a resistance will cause the levers 33 to force the brake-beam andbrake-shoes toward the wheels at that end of the truck. At the same timethe pull exerted upon the rods 35 willbe transmitted to the levers 33 atthe other end of the car to cause the brake beam and shoes thereat to bealso drawn toward the wheels.

It will be seen that the levers are so arranged and connected that whenthose at one end of the truck are operated by the pull of the rods 35the lever 36 at such end is drawn inwardly against the brake-beam, whicharrests its movement, whereupon said lever, beam, and neighboring levers33 become practically a rigid construction.

The system of levers at one end of the truck may be omitted and thesystem at the other end operated by connecting the rods 35 with anystationary support to serve as a re sistance.

My invention, although particularly adapted for railway-cars, isapplicable to various styles of vehicles.

What I claim as new, and desire to secure by Letters Patent, is-- abrake-operating lever pivoted at one end to the middle of thebrake-beam; anda link connecting said operating-lever with one of thelevers of said pair; and links connecting each of the levers of saidpair with its corresponding lever on the same side at the opposite endof the truck, substantially as described.

In testimony whereof I have hereunto set my hand this 2d day of October,1901.

CHARLES W. POWELL. Witnesses:

FRANK C. CURTIS, E. M. OREILLY.
